Lesson 2.1 – Digestion – From the mouth to the bloodstream

In this lesson we will review and expand on student knowledge of digestion and absorption. The main objective is for students to be able to describe process of digestion in each of the main organs, including select digestive enzymes. They should also be able to compare and contrast digestion and absorption of carbohydrate, fat, and protein rich foods. We also use examples of common digestive problems to illustrate structure-function.
